Disinfection is a procedure which destroys‚ inactivates or removes potentially harmful microbes- without necessarily affecting other organisms

The Causes of Disease in Humans Diseases can be caused in humans in many a way. Some diseases may be pathogenic some may be caused by a lifestyle choice of an individual or an individual surrounding them‚ or some may be genetic. Pathogens are micro-organisms which cause disease some bacteria‚ fungi and all viruses are pathogens. Pathogens enter our bodies through various methods such as breaks in the skin‚ the digestive system‚ and respiratory system. Pathogens can survive in many conditions

The world is exist with germs of all kinds especially viruses and bacteria. Most of the time human bodies do a wonderful job of fending off these microbes. This sort of self-defense is due to the immune system‚ which detects any pathogen also known as disease-causing agent and attacks it with immune foot soldiers including macrophages‚ lymphocytes and phagocytes. Specifically‚ over 700 different strains of bacteria have been discovered in the human mouth‚ though most people are only host to 34 to

Use the information presented in this module along with additional outside research to answer the questions: 1 Discuss the two methods of viral replication. The two methods of viral replication are done in animal viruses. The first method deals with DNA viruses and the second is RNA viruses. In the DNA virus‚ the viral DNA enters the nucleus of the host cell. Than it is transcribed into mRNA and leaves the nucleus into the cytoplasm. The early mRNA then translates into early viral proteins. The early

What is a Virus A virus s a small‚ NONLIVING particle that invades and then reproduces inside a living cell. Viruses are considered nonliving because they are not cells. They cannot: * use energy to grow * make food * take in food * produce waste Like living organisms: they do multiply. Examples of Viruses There are many viruses in the world. We have all experienced
